C'est quoi cette antiquité ? Ce modèle ressemble beaucoup à celui-ci que j'avais photographié à Telluride (Colorado) :

What made Crowns so special? In a word – toughness – these buses were legendary for their strength, robust construction, and longevity. While most of Crown’s competitors used 45,000 psi steel, Crown’s floorpan and framework were constructed of 90,000 psi ultra high tensile steel sheathed with heat-treated aluminum bodywork. The Super Coach’s double-walled steel body structure was both bolted and welded to outriggers on the main chassis which was built using nested channel frame rails and cross-members.
Multiple body posts protected both ends of the coach and the roof of the 35’ model was made up of 22 roll bars spaced 17 ½” apart. The 40’ Super Coach used 26 roll bars, all constructed of the firm’s 90K psi 12 gauge steel.
Yes, this was one tough bus…….and Crown backed that up with an unprecedented 20-year/100,000 warranty on all of their coach bodies (later increased to 20-years/150,000 miles).
In addition to single axle models, Crown also built larger tandem axle versions that could seat up to 97 students……
Super Coaches were mid-engined and used horizontal Hall-Scott 779 cu in gasoline or Cummins 743 cu in NHH “pancake” diesel engines. Later versions used mostly Cummins NHH 855 cu in diesels. The Hall-Scott engines, though offering poor gas mileage, gave these buses good power.
